Objectives We evaluated the improving effects of Taeksa-tang (TST) using 3T3-L1 cells and C57BL/6 mice were fed on a high-fat diet. Methods The anti-radical activities of TST were studied using 2,2-diphenyl-1-picrylhydrazyl and 2,2'-azino-bis (3-ethylbenzothiazoline-6-sulphonic acid). The content of total polyphenol was measured using Folin-Ciocalteu reagent, whereas aluminum chloride colorimetric method was used for the content of total flavonoid. Moreover, the factors related to lipid profile and the protein expressions such as 𝛽-oxidation and anti-oxidant enzyme were analyzed using serum and western blotting of 3T3-L1 cells. Additionally, we examined lipolysis through glycerol appearance in mouse adipose tissue. Results TST treatment showed strong free radical scavenging activities with half maximal inhibitory concentration and the presence of a amount of total polyphenol and total flavonoid. TST treatment significantly increased factors related to 𝛽-oxidation such as carnitine palmitoyl transferase-1 and uncoupling protein 2 via the phosphorlyation of liver kinase B1 (LKB1) and AMP-activated protein kinase (AMPK). Moreover, the protein expressions of anti-oxidant enzyme and lipolysis were significantly elevated by TST administration. In addition, TST supplementation lowered serum malondialdehyde, triglyceride, and total cholesterol levels compared with the control group. Taken together, these data suggest that TST treatment regulated lipid parameters via the increase of 𝛽-oxidation by LKB1-AMPK signaling pathway. Conclusions TST may have a potential remedy in the prevention and treatment of obesity. Therefore, this study may provide the scientific basis for TST use.

HK shiitake mushroom mycelium (HKSMM), containing 14% β-glucan, is a health functional food ingredient approved individually for liver health by the Ministry of Food and Drug Safety. The immune-enhancing efficacy of a 50% aqueous ethanol extract of HKSMM (designated HKSMM50) was studied in Jurkat cells activated with concanavalin A (ConA). Active hexose correlated compound (AHCC) was used as a positive control. ConA-activated Jurkat cells were treated with HKSMM50 (0, 25, 50, 100 ㎍ g/ml) or AHCC (100 ㎍ g/ml), and cultured for 3 and 6 hours. The nuclear factor of activated T cells (NFAT) protein content in the cytosol and the nucleus was measured by Western blotting. Interleukin-2 (IL-2), interferon-gamma (IFN-γ), and cyclooxygenase-2 (COX-2) were determined using enzyme-linked immunosorbent assay (ELISA) kits. HKSMM50 lowered NFAT content in the cytosol, but elevated NFAT content in the nucleus. The IL-2 and IFN-γ productions were elevated. Meanwhile, both COX-2 activity and apoptosis were suppressed. The efficacy of the AHCC treatment showed similar to those of HKSMM50 treatments. These results indicate that the HKSMM50 exhibited immune-enhancing effects in ConA-treated Jurkat cells by activation of NFAT protein, and suggest that HKSMM could be used as a health functional food ingredient to improve immune functions in humans.

To determine the toxic effects of the mirror carp, Cyprinus carpio nudus on waterborne nitric acid exposure, they were exposed to waterborne nitric acid at 0, 4, 20, 100, 500, and 2,500 mg NO₃^-/L for 96 h. The semi-lethal concentration (LC₅₀) of the scented fish by 96 hours of acute exposure to nitric acid was 1,433.54 mg NO₃^-/L. The physiological changes of waterborne nitric acid exposure on mirror carp were evaluated through hematologic properties, and RBC count showed a significantly decreased (p < 0.05). The change in the ion control ability of the mirror carp according to exposure to waterborne nitric acid was evaluated through the plasma inorganic component, and calcium and magnesium were significantly decreased (p < 0.05) in the plasma inorganic component. The health and stress status of the mirror carp due to exposure to waterborne nitric acid were evaluated through plasma organic ingredients, and the plasma organic component glucose showed a significantly increase (p < 0.05). Changes in liver damage and enzyme activity due to waterborne nitric acid exposure were evaluated through plasma enzyme components, the enzymatic activities of plasma AST, ALT, and ALP were significantly decreased (p < 0.05) in high levels of waterborne nitric acid exposure. The results of the present study suggest that waterborne nitric acid exposure to C. carpio nudus can toxicly affect survival, hematologic properties, and plasma components.

Citrullinemia type1 is an autosomal recessive disorder of the urea cycle characterized by neonatal or late onset of hyperammonemia caused by a deficiency of the enzyme argininosuccinate synthetase (ASS). An ASS1 deficiency demonstrates fatal clinical manifestations that are characterized by the neonatal metabolic coma and early death when untreated. It causes a broad spectrum of effects, ranging from a mild disorder to a severe mental retardation, epilepsy, neurologic deficits. An acute neonatal form is the most common. Infants are normal at birth followed by an acute illness characterized by vomiting, lethargy, seizures and coma. These medical problems are life-threatening in many cases. A later onset form is less frequent and may be milder than the neonatal form. This later-onset form is associated with severe headaches, visual dysfunction, motor dysfunction, and lack of energy. Citrullinemia type1 is caused by mutations in the ASS1 gene located on chromosome 9q34.1 that encodes argininosuccinate synthetase, the third enzyme of the urea cycle catalyzing the formation of argininosuccinic acid from citrulline and aspartic acid. The enzyme is distributed in tissues including liver and fibroblasts. This mutation leads to hyperammonemia, arginine deficiency and elevated citrulline level. In the urea cycle, argininosuccinate synthetase catalyses the conversion of citrulline and aspartate to argininosuccinate.. Here, we describe a female newborn patient with lethargy, rigidity and hyperammonemia who was diagnosed as citrullinemia type1 with a c.[421-2A>G], c.[1128-6_1188dup] mutation.

Background: Angiotensin converting enzyme is a glycoprotein peptidyldipeptide hydrolase which cleaves the c-terminal dipeptides of several oligopeptides. It is a menbrane-bound protein mainly synthesized by the endothelial cells. Since the lung has the largest capillary bed of any organ in the body, it is here that ACE acts on circulating substrates like angiotensin I and bradykinin. It is well known that ACE correlates with disease activity in sarcoidosis and also there are reports that changes in serum ACE activity are found in many acute and chronic lung diseases. So we planned this study to see if serum ACE activity can act as a prognostic factor in lung cancer. Methods: Forty-one newly diagnosed lung cancer patients were included in the study group. There were 19 patients with squamous cell lung cancer, 13 with adenocarcinoma, and 9 with small cell carcinoma. Patients were excluded from the study if they had high blood pressure, heart disease, liver disease, renal disease, or other lung disease. Serum ACE activity was analyzed according to cell type, staging, mode of treatment, and clinical response to treatment. Results: 1) There was no difference in serum ACE activity between lung cancer patients and the control group. Also no difference in serum ACE activity was found according to cancer cell type or staging. 2) In patients who underwent curative resection of lung cancer, serum ACE activity was decreased significantly after the operation. 3) In patients who were diagnosed as non-small cell lung cancer and were treated with 4 cycles of anti-cancer chemotherapy without clinical improvement, changes in serum ACE activity were not seen after the treatment. 4) In patients diagnosed as small cell lung cancer treated with 4 cycles of anti-cancer chemotherapy with clinical improvement, changes in serum ACE activity were also not observed. Conclusion: Serum ACE activity was decreased after lung resection but had no relation to cell type, staging, or clinical response to treatment in lung cancer patients. Therefore, serum ACE activity is not suitable in predicting clinical outcome of lung cancer patients.

The purpose of this study was to investigate whether enzyme-hydrolyzed poultry by-product meal (EHPBM) is more effective as a protein source than poultry by-product meal (PBM) and soybean meal (SBM) for broiler chickens. A group of 300 one-day-old broiler chicks was randomly allocated to three treatments with five replicates (20 birds/replicate) for five weeks. The treatments consisted of basal diets containing 1) SBM, 2) PBM, and 3) EHPBM. The EHPBM-fed group (1,853 g±125.60) showed the highest final body weight (P<0.05) when compared to the PBM-fed group (1,723 g±76.81) and SBM-fed group (1,545 g±62.31). The feed conversion ratio of the EHPBM treatment group (1.740±0.104) was significantly higher (P<0.05) than those of the SBM (1.653±0.056) and PBM groups (1.674±0.072). It can be speculated that the increased feed intake in the EHPBM group led to higher body weight gain and FCR. There was no significant effect of treatments on internal organ weight except for the bursa of Fabricius. Blood biochemical characteristic analysis showed that aspartate aminotransferase and alkaline phosphatase levels were higher in the EHPBM and PBM groups (P<0.05), probably due to the strained liver caused by the rapid growth of birds. In conclusion, EHPBM may partly replace conventional dietary protein sources such as soybean meal or poultry by-product meal and can be used to improve the productivity of broilers.

Squalene synthase plays an important role in the cholesterol biosynthetic pathway. Inhibiting this enzyme in hypercholesterolemia can lower not only plasma cholesterol but also plasma triglyceride levels. A squalene synthase inhibitor was screened from Prunus mume fruit, and then purified via sequential processes of ethanol extraction, HP-20 column chromatography, ethyl acetate extraction, silica gel column chromatography, and crystallization. The squalene synthase inhibitor was identified as chlorogenic acid with a molecular mass of 354 Da and a molecular formula of $C_{16}H_{18}O_9$ based on UV spectrophotometry, $^1H$ and $^{13}C$ NMRs, and mass spectrometry. Chlorogenic acid inhibited the squalene synthase of pig liver with an $IC_{50}$ level of 100 nM. Since chlorogenic acid was an effective inhibitor against the squalene synthase of an animal source, it may be a potential therapeutic agent for hypercholesterolemia.

The aim of this study was to investigate the effect of atrovasatatin on the pharmacokinetics of nicardipine after oral and intravenous administration of nicardipine to rats. Nicardipine was administered orally (12 mg/kg) or intravenously (i.v., 4 mg/kg) without or with oral administration of atrovasatatin (0.3 or 1.0 mg/kg) to rats. The effect of atorvastatin on the P-glycoprotein (P-gp) as well as CYP3A4 activity was also evaluated. Atorvastatin inhibited CYP3A4 enzyme activity in a concentration-dependent manner with 50% inhibition concentration ($IC_{50}$) of 48 ${\mu}M$. Compared to the controls (nicardipine alone), the area under the plasma concentration-time curve (AUC) of nicardipine was significantly (1.0 mg/kg, p<0.05) greater by 16.8-45.4%, and the peak plasma concentration ($C_{max}$) was significantly (1.0 mg/kg, p<0.05) higher by 28.0% after oral administration of nicardipine with atorvastatin, respectively. Consequently, the relative bioavailability (R.B.) of nicardipine was increased by 1.17- to 1.45-fold and the absolute bioavailability (A.B.) of nicardipine with atrovasatatin was significantly greater by 16.7-20.9% compared to that of the controls (14.3%). Compared to the i.v. control, atrovasatatin did not significantly change pharmacokinetic parameters of i.v. administration nicardipine. The enhanced oral bioavailability of nicardipine by atorvastatin suggests that CYP3A subfamily-mediated metabolism were inhibited in the intestine and/or in the liver rather than P-gp-mediated efflux of nicardipine. Based on these results, modification of nicardipine of dosage regimen is required in the patients. Human studies are required to prove the above hypothesis.

This study was performed to investigate the anti-obesitic effect of mulberry root-bark on male and female Zucker FA/FA or FA/fa rats. Obesity in the rats was induced by feeding high-lipid diet contained 3% corn oil and 1% cholesterol. Experimental groups in male and female rats were assigned to normal diet group (normal control), high-lipid diet group(positive control) and 3% mulberry root-bark powder in high-lipid diet group (MRC). The mulberry treated-group showed decreases of body weight, FER (food efficiency ratio) value and lipid peroxidation in the liver and increase of high density lipoprotein cholesterol (HDL-C) value, compared with positive control groups. Our findings suggest that mulberry root-bark has a potential role in preventing or improving obesity from the following points of view, body weight, serum lipids and antioxidant enzyme activities.
